[Dovecot] sieve_execute_bytecode failed with squirrelmail

[Gregory Charot (EVENIUM)]

Hello all,

I'm using dovecot on CentOS 5.8 (official CentOS package) and have lot 
of lock and "sieve_execute_bytecode error" in my dovecot.log.

$ cat /etc/redhat-release
CentOS release 5.8 (Final)

$ dovecot --version
1.0.13

The sieve scripts are generated by squirrelmail mail and are mostly mail 
filters and vacations notices.

$ yum info squirrelmail.noarch
Installed Packages
Name       : squirrelmail
Arch       : noarch
Version    : 1.4.8
Release    : 5.el5.centos.13

When I look at my dovecot.log I have a lot of sieve error :

deliver(foo): Sep 11 15:08:04 Info: 
msgid=<1881992580.96697.1347363282479.JavaMail.jboss at gula1.xxx.com>:

Generic Error
deliver(foo): Sep 11 15:08:04 Error: 
sieve_execute_bytecode(/home/foo/.dovecot.sievec) failed


The server hosts around 50 mailboxes, some people does have sieve errors 
some doesn't.

Is there any way to get more details about the runtime error ? How can I 
debug this issue ?

Thanks a lot in advance,
Greg
